I have a component and there is no chassis grounding to ground it. The only way to ground this component is to use electircal wire through the connector and attach it to an external ground.
Now I need to find out how long the chassis wire and how big the wire gauge should be to meet the impedance value of 2.5 milli ohms for the frequency range of 100kHz to 2GHz.
Assuming for a copper 22 gage wire at 20'C:
For the DC resistance I know that it is
Resistance = Resistivity * Length / Area.
How about for the AC part?
Is it: Impedance Z = 2*pi*F*L + 1/(2*pi*F*C) + R,
where F is the frequency, L is the inductance and C is the capacitance.
How do I calculate the L and the C? Actually is the C even needed since the Frequency is high that component will just go to 0 right?
Any help would be appreciated.
Thanks!
